Working Principles
The MAX634ESA+T is designed to monitor the supply voltage of a digital system. It compares the supply voltage with the programmed threshold voltage and asserts the reset output when the supply voltage falls below the threshold. The reset output remains asserted until the supply voltage rises above the threshold or a manual reset signal is applied. The device also includes a watchdog timer that requires periodic feeding to prevent it from timing out. Additionally, a power-on reset delay can be introduced using an external capacitor to ensure stable operation during power-up.
